Electrical Diagnostics

Utilizing advanced UHF technology, the PDMG–R system is designed for large EHV GIS installations. It collects PD data from UHF sensors (couplers) installed on the GIS and transmits the information to software for automatic interpretation and analysis by propriety HQ Software – allowing incipient faults to be avoided and the condition of the long term health of the insulation system to be simply and effectively monitored over the life of the GIS.

DFR, DDR, PMU, TWS FL and Class A PQ in one device! A multifunction substation monitor offering advanced fault recording and long duration disturbance monitoring with options of phasor measurement in compliance to the IEEE C37.118 2005 specification; the most accurate fault location available using traveling wave methodology and Class A power quality in compliance with IEC 61000-4-30 Class A (Edition 2.0)

The CT17 wide-band current transformer is designed to acquire partial discharge (PD) pulses from generator or motor windings with installed Surge Capacitors. The CT17 has to be installed on the ground wire of the surge capacitor. For this, the case of surge capacitor has to be insulated from the ground, that just the ground wire is connected to the main ground. The measurement is contact free. No galvanic connection to the high voltage terminals is made.

Transport to site, connect and gather data – it’s that easyA portable version of the well established 61850 compliant BEN6000 multifunction recorder offering fault recording, slow scan recording and continuous recording with the option of power quality and phasor measurements.

The CT85 wide-band current transformer is designed to acquire partial discharge (PD) pulses from generator or motor windings. Its high saturation current and intrinsic suppression of very low frequencies makes it an ideal sensor for installation around high voltage power cables. The measurement is contact free. No galvanic connection to the high voltage terminals is made.

Easy-to-use Partial Discharge Monitoring SystemMICAMAXX®pda is a partial discharge trending system comprising an on-line monitoring unit and PD transducers, which are fitted to the machine as a permanent installation to enable continuous on-line monitoring of the insulation system. Partial discharge sensors, such as coupling capacitors and high frequency current transformers are available for all HV-machine rated currents and voltages. And of course, they can be installed in hazardous environments
